Background

Status: Approved
Date Posted: Aug 1, 2011
Sponsor: Morgan Stanley
Urgent: No
Sections: 4.4.7.4, 6.4.8.2, 6.7.2, 6.7.3
Description: This Nodal Protocol Revision Request (NPRR) allows the Supplemental Ancillary Services Market (SASM) to be operated as a balance of the day market for Ancillary Services.
Reason: The current market locks entities in once they have sold Ancillary Services to ERCOT in the Day-Ahead Market (DAM). Conditions often change after the close of the DAM and Real-Time. This NPRR would allow Qualified Scheduling Entities (QSEs) the ability to modify their responsibilities and optimize the use of their Resources.
